We traded our 36' fifth wheel, and truck, for a 31' class C. Many reasons but have found the C much easier to park, get gas, back up, etc. Although the room in the 5th was more we really don't miss it as we only travel a couple of times a year and it is just the two of us and our two small dogs. Gas mileage is about the same so that is not a concern. One thing you will need if you go with a C is the replace the shocks with monroe or bilstein, install a sway bar and front (and maybe rear) stabalizers jacks. Just look them over and get one that you are comfortable with the floor plan.
